Glossary

Here is a listing of the most common devices in the realm of surface-mounted devices:

BGA‘s come in many different configurations.

CBGA, (Ceramic Ball Grid Array). The thickness and depth are maximum dimensions. The solder balls are made of a high melt non-eutectic composition (10% Sn/ 90% Pb).

DSBGA, (Die Size Ball Grid Array). DSBGA is a type of BGA package where the body size is defined to coincide as closely as possible with a specific die size. These packages are sometimes called CSP packages. The solder balls consist of eutectic lead/ tin solder.

FBGA, (Fine Line or Fine-Pitch Ball Grid Array). These are BGA packages with grid pitches less than 1.0 mm. These devices use Flip-Chip interconnect technology and are sometimes called Chip Scale Packages. The solder balls typically consist of Eutectic lead/tin solder.

TBGA, (Tape Ball Grid Array). TBGA packages are made from strips of Polyamide tape. A metal plate “stiffener” is incorporated on top of the package for added strength. The nominal solder ball diameter for high melt solder balls is 0.63 mm and 0.60mm for low melt.

UBGA, (Ultra Fine Line BGA).

MSOP-08 (2.30) is also sometimes known as TSOP2-08 (2.30) package.Odd-Form – Odd-Form DevicesOscillator – A circuit or device that produces an alternating current of a specific frequency at its output terminals.PDIP – Plastic Dual In-line PackagePFP – Plastic Flat packsPGA – Pin Grid ArraysPKDIP – Plastic Skinny Dual In-line PackagePLCC – Plastic Lateral Chip Carrier, (sometimes PQCC). The standard lead pitch on each is 1.27 mm.QFP – Quad Flat pack, a package with leads on all four sides. It can be ceramic, metal or plastic; bumpered. Devices are named for their body width, length, and thickness, (none includes leads), followed by their lead pitch and version, if applicable.QFN – Quad Flat No Lead Packages (QFN) or VQFN Very Thin, or Micro Lead frame Quad (MLPQ)-Very Thin (HP-VQFP-N, Thickness-1.0 mm), Very Very Thin (HP-WFQFP-N,-Thickness-0.8 mm), Ultra-Thin-0.65, Extremely Thin-0.5mm)QSOP – Quarter-size Small Outline Package, [See: SSOP]. The body width is indicated in the parentheses.
QVSOP – Quarter-size Very Small Outline Package.SKSJ – Socket for SOJSMC‘s – Super Miniature Case Rectifiers. These are two leaded C-bend devices. They are primarily used in Diode and Rectifier applications. JEDEC designator: R-PDSO-C2SMCGs – Super Miniature Case Rectifiers. These are essentially SMCs, but with gull wings as opposed C-bend leads. They are primarily used in Diode and Rectifier applications. JEDEC designator: R-PDSO-G2SOD – Small Outline DiodesSIP – Single In-line PackageSKPQ – Socket for PQCCSOIC – Small Outline Integrated Circuit. SOIC-08 (5.30) and SOIC-16 (4.57) are not JEDEC approved package styles, but nonetheless are commonly used.SQFN – Plastic Quad No-Lead Staggered Multi-Row Packages. JEDEC Designator-HP-WFQFP-N & HP-UFQFP-N. They come in three styles: 2-row without ring, 2-row with ring, and 3-row without ring. The number of leads are maximum leads; depopulation is allowed.SOT – Small Outline Transistor. SOT-143 has multiple pitches: 1.92 & 1.72 mm. Leads go to the right on SOT-089 and down on SOT-223SSOP – Shrink Small Outline Package. The body width is indicated in the parentheses. [Note: SSOP-36 (5.3) is not a JEDEC approved package style, but nonetheless is commonly used].Through-Hole (Axial) – Through hole Devices: Axial Technology. Devices with body diameter less than 5 mm classify as “Axial B = 53”, body diameter greater than 5mm, but less than 10mm classify as “Axial B = 63”.
